The United States is concerned about China's space combat capabilities, so what does competition in satellite orbit and China's ability to practice the display of 21 satellites mean for U.S. hegemony?
The United States has a website dedicated to the field of military defense, all kinds of breaking news, called Breaking Defense. On October 28, this website reported that the incident actually came out in July this year, but it was recently revealed that in July, a US satellite for space surveillance, numbered USA-271, was in flight and consciously approached China's practice-20 satellite. From the flight trajectory map published on the US website, USA-271 is close to the practice-20 after the orbit change, and then close to the close, and maintain a parallel flight, the two satellites together around the earth in a circle, and then that is about 24 hours, the practice-20 began to change orbit, stupid.
China's practice-20 satellite is an eight-ton experimental communications satellite, known as China's most advanced and largest communication satellite. Then the Americans were also surprised, saying that a satellite as large as China deftly carried out orbit change actions, and it was cleverly chosen the timing of orbit change, so that the satellite moved to the U.S. monitoring system, undetectable position, and then the orbit change action was taken. So when the United States observes the Chinese satellite again, it will be too late to keep USA-217 tracked.
Then the Americans believe that China's operation shows a high-precision tracking level, as well as the satellite's ability to change orbit, on the other hand, the article also mentions that the United States is also highly concerned about another Chinese satellite, this satellite is launched in 2018, communication technology experiment 3. Then they think that this satellite is a Chinese reconnaissance satellite, or part of the early warning system, and after the launch, they also released a sub-satellite, saying that this satellite, in more than two years, has undergone four orbit changes, but the orbit of this sub-satellite has not moved. Of course, some people think that it is not a sub-satellite, that is, a rocket wreckage thrown away during the launch, which has been treated as a satellite, and that there are more rocket wreckage in the outer orbit of the earth, so it is not surprising.
Followed by the Shijian-21 satellite launched two days ago, according to the China Academy of Aerospace, Shijian-21 is mainly used for space debris to slow down technical verification. And we have also announced a technology, called "non-cooperative target rendezvous technology", what is called non-cooperative target, this United States also understands, this data is played out by the Americans, to put it bluntly, found a target, this target should not answer me nor cooperate with me, so such a target is not the enemy's, or it is not under our control, so how to get close to this uncooperative target, how to deal with how to rendezvous, what is the rendezvous, after the rendezvous is to use the mechanical arm to arrest.
Speaking of robotic arms, we have a lot of public papers to discuss, how to go to space robotic arms in space, catch non-cooperative targets, to put it simply, according to our public statement, after this satellite goes to the sky, it is to clean up all kinds of space orbit garbage, so american satellites must worry about one thing, who do you say is garbage?
In fact, as soon as this matter is talked about, it goes back to the Cold War period, the 1967 version of the movie "007" has fantasized about launching rockets to capture each other's satellites, and the Star Wars plan that the Americans later engaged in also has these contents, but science fiction is good or planned, in fact, the United States has also conducted some experiments, but has not turned the idea into actual combat capabilities.
I still want to use the space shuttle to go up, catch other satellites, now the space shuttle is gone, let alone fly to the geosynchronous orbit to catch the satellite, so now many of the Americans' ideas, either to give up or to tear down and start over, and then suddenly found that China has let the practice of satellites, in the orbit even run with chase, but also wielding big pliers, the United States THAT TV series "Space Force", reflects the anxiety and anger and helplessness, but also from another angle.
In the field of space competition, the concern about China's development, in reality, is that if it loses its extra-atmospheric superiority, many of the United States' military technology, tactics and military thinking will now lose its pillars. Space and oceans, satellites and aircraft carriers, the United States' strategic layout in the world to support, rely on these two areas, these two areas, even if not surpassed, as long as they are chased to the same level, the United States' global hegemony has no foundation.
